Description

With the latest lattice QCD calculations on form factors of $B_c\to J/\psi$, we use non-relativistic QCD to fit tensor form factors. Using the fitted form factors, we study different model-independent New physics scenarios and $R_{2}$, $U_{1}$, $S_{1}$ leptoquark model and give the predictions of $R_{J/\psi}(q^2)$, $P_\tau^{J/\psi}(q^2)$, $P_{J/\psi}(q^2)$ and $\mathcal A_{FB}^{J/\psi}(q^2)$ in allowed new physics scenarios and leptoquark model.
